Description:Like it's predecessor, Proofs without Words, It is a collection of pichtures or diagrams that help the reader see why a particular Mathematical statement may be true, and how could one begin to go about proving it. While in some Proofs without words an equation or two may appear to help guide that process, the emphasis is clearly on providing visual clues to stimulate mathematical thought. The Proofs in this collection are arranged by topic into five chapters: geometry and Algebra; trignometry, calculas and analytical geometry; inequalities; integer sums and sequences and series. Teachers will find that many of the proofs in this collection are well suited for classroom dis discussion and helping students to think visually in mathematics.
